Outline of Final Research Achievements |
We identified the actin-binding protein cortactin as a substrate of protein tyrosine phosphatase σ (PTPRσ). PTPRσ was activated by chondroitin sulfate and dephosphorylated cortactin. As a consequence, the autophagy flux was disrupted at the step of autophagosome-lysosome fusion. In addition, we succeeded in comprehensive screening of PTPRσ substrates. Our study provided solid evidence of the direct relationship between PTPR and autophagy. Considering that autophagy dysfunction is involved in various disorders such as neurodegenerative diseases, our results may influence a broad spectrum of research fields.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、PTPRとオートファジーの関連について直接のエビデンスを示す意味で重要である。加えて、これまで糖鎖は細胞表面で様々な分子と結合・相互作用することを主な役割とするという概念が定着しており、細胞内シグナルを動かすようなリガンド糖鎖の存在は予見されてはきたものの、それを示す直接のデータは乏しかった。本研究によってそれが示された意義は大きい。また、オートファジー不全はパーキンソン病やアルツハイマー病などの神経変性疾患で深く関与している。がんでもオートファジーと病態の関係が分かっている。これらを考え合わせると、本研究は多様な分野へ影響を与える基盤的研究となる。
